2 Claims.

This invention relates to smoking pipes. It is particularly directed toa water cooled smoking pipe. 7

An object of this invention is to provide a highly improved smoking pipeof the character described comprising a stem to which the bowl isattached and a bit fitted within the rear end of the stem, said stemextending forwardly beyond the bowl, and being provided with a chamberinto which cooling liquid may be inserted through the front or near endof the stem, and the opening through which the water is inserted beingclosed by a removable cap.

Another object of this invention is to provide in a smoking pipe of thecharacter described, a stem having a smoke passage passing through thewater chamber and connected to the top of the stem by a fin which actsto dispel heat, the

smoke passage being otherwise surrounded by cooling liquid in thechamber which also serves to cool the smoke going through the passage.

Still another object of this invention is to provide in a smoking pipeof the character described, a stem provided with a liquid chamber whichhas only one opening, the stem having an inlet opening for insertingcooling liquid into said chamber, said opening being closed by a screwcap, the arrangement being such, furthermore, that when the screw cap isremoved for inserting liquid into the liquid chamber, the smoke passageis not disturbed, that is, the opening for the liquid chamber isseparate and apart from the smoke passage.

Yet another object of this invention is to provide in a smoking pipe ofthe character described, a stem which may be readily manufactured as asingle metal die casting, and includes a smoke passage, a liquid chambersurrounding said smoke passage, a filter chamber at one end of the smokepassage and communicating therewith, a cooling fin connecting said smokepassage with the top wall of the stem, a seat for the pipe bowl, apassage extending from the smoke passage to the pipe bowl, an openingfor the cap which closes the liquid chamber, and standing ribs on thelower wall of the stem, so that the pipe may be supported on a table.

A still further object of this invention is to provide a strong, rugged,compact, and durable pipe of the character described, which shall give acool smoke, which shall be easy to clean, which is so constructed thatwater or other cooling liquid may be readily inserted or removed, whichshall be relatively inexpensive to manufacture, attractive inappearance, and yet practical and efiicient to a high degree in use.

Other objects of this invention will in part be obvious and in parthereinafter pointed out.

The invention accordingly consists in the features of construction,combinations of elements.

2 and arrangement of parts, which will be exemplified in theconstruction hereinafter described, and of which the scope of inventionwill be indicated in the following claims.

In the accompanying drawing in which is shown an illustrative embodimentof this invention,

Fig. l is a top plan view of the smoking pipe, with the bowl partlybroken away, embodying the invention;

Fig. 2 is a cross-sectional view taken on line 2-2 of Fig. 1;

Fig. 3 is a cross-sectional view taken on line 33 of Fig. 2, and

Fig. 4 is a cross-sectional view taken on line 4-4 of Fig. 2.

Referring now in detail to the drawing, l0 designates a smoking pipeembodying the invention. The same comprises a stem II, a bowl l2,attached thereto by means of a screw l3, a cap I4 to close a chamber l5for cooling liquid, formed in the stem, and a mouth bit I6 frictionallyfitted withinthe rear end of the stem, and carrying a filter IT.

The stem ll may be made as a single member and is so constructed that itmay be manufactured as a single die casting of suitable metal, such asaluminum or the like light metal. The stem l i may be provided withparallel side surfaces 20. It is formed with a curved under surface 2|and with parallel ridges 22 at the lower ends of the surfaces 20 and atthe sides of the curved surface 2| forming standing ridges or ribs onwhich the pipe may be rested on a flat surface. The stem is formed atits front end with an internally threaded opening 23 and with aninternal shoulder 24 at the inner end of the opening 23. The opening 23communicates with the chamber 15 which extends rearwardly of saidopening. The front end of th chamber [5 may be of circularcross-section. The stem is formed with a top wall 25 from which extendsdownwardly a longitudinal, radial web or fin 26. The front end of thefin 26 is spaced rearwardly from the shoulder 24, and the rear end ofthe fin is spaced forwardly of the rear end of the stem ll. At the lowerend of the fin 26 is a longitudinal coextensive portion 21 of enlargedcircular transverse cross-section, and formed with a through smokepassage 28. Adjacent the front end of the fin 26 is a vertical ortransverse passage or bore 29, communicating with the front end of thesmoke passage 28. The passage 29 extends to the upper side of the stem.Thus, the chamber [5 surrounds the fin 26 and portion 21 which is formedwith the smoke passage. At the rearward end of the liquid chamber I5 isa transverse annular wall or partition 3| closing the chamber. Thus, therear end of the fin 26 meets the annular wall 3| and its front endterminates at the rear end of the large front end portion of the chamberl5. The web or fin 2'6 divides the chamber into two spaced channels asseen in Figs. 3 and 4 of the drawing.

The stem H i formed at its rear end with a tapered opening 33. Extendingfrom the tapered opening 33 is a filter pocket or chamber 34 whichcommunicates with smoke passage 28.

At the top surface of the stem is a pair of arcuate grooves 35concentric with respect to the passage 29 for the purpose hereinafterappearing. The upper end of the passage 29 is internally screw threadedas at 38 for the purpose hereinafter set forth.

The screw cap id has an externally screw threaded portion 4E) screwedwithin the threaded opening 23. Said screw cap furthermore, has a headll which is knurled to facilitate turning the cap. A washer :32 may beinterposed between one end of portion at of the cap and the shoulder 24.

The bowl it may be made of wood or of any other suitable material. is anannuiar ridge received in the grooves 36. It is also formed with acentral opening 'i registering with the opening 38. The screw 13 whichattaches ti e bowl E2 to the stem has a head 43 contacting the bottom ofthe bowl, and a screw threaded stem dd screwed into the threaded opening38. The screw has a through opening 59 which communicates with the smokepassages 2e and 28.

The bit it; has a tapered portion 52 which fits into the tapered opening33 in the stern. Said bit is formed with a through passage 53 having anenlarged passage at its front end forming a socket into which the rearend of the filter ii is frictionally fitted. The filter [1 projects intothe filter chamber 34 of the stem, as shown in the drawing,

It will now be understood that water or other cooling liquid may bepoured into the chamber or jacket for cooling the smoke, as it passesfrom the bowl through the passages 29, 28 and 34 to the hit i6. It willbe understood that the stern extends beyond and under the bowl. Thecooling liquid is poured into the front end of the stem. The smokepassage is supported by the fin and connected thereby with the top wallof the stem and is surrounded by the cooling medium. The internal finalso acts to dispel heat. that is, the inlet opening. It will be furtherunderstood that when the cap is removed to insert water or other coolingliquid, the smoke passage is not disturbed, and that is so because theopening for the liquid is separate and apart from the smoke passage. Itwill also now be understood that the stem ll may be made as a single diecasting, and includes the smoke passage, the chamber for the coolingliquid, the filter cham- Formed at its underside" The liquid chamber hasonly one opening,

ber, the cooling fin, the bowl seat, the opening for the bit, theopening which receives the cap for closing the chamber for the coolingliquid, and it also includes thestanding ribs. 22. Thus, the single diecasting includes a number of elements of the pipe.

t will thus be seen that there is provided a device in which the severalobjects of this invention are achieved and which is well adapted to meetthe. conditions of practical use.

As various possible embodiments might be made of the above invention,and as various changes might be made in the embodiment above set forth,it is to be understood that all matter herein set forth or shown in theaccompanying drawings is to be interpreted as-illustrative and not in alimiting sense.

Having thus described my invention, I claim as.

new and desire to secure by Letters Patent:
